To all whom it may concern.-

Be it known'that I, GEORGE ROTH, a citizen of the United States, residing at Highland, in the county of Madison and State of Illinois, have invented a certain new and useful Improvement in Machines for Liquidizing Canned Milk, of which the following is a specification.

My object is to overcome or neutralize the jarring usual to such machines; and it consists in providing a machine with means of actuating the chests always in opposite directions from each other at the same time, and in the arrangement and combination of parts herein described and claimed. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my machine. Fig. 2 is a plan view of the same. Fig. 3 is a side elevation of the eccentrics detached from the shaft.

A is the frame-work of the base of my machine, and carries the shaft, pulleys, and reciprocating rods, and to which are attached uprights A AA A, which rise from thetop of the frame-work A and connect with the upper frame A.

A is a frame-work situated above the frame A, and serves to support the reciprocating chests C and C. It is braced to the frame A by the brace-rods B B B B. At each corner of this frame A is attached a hinge H, which hinges are adapted to hold supporting-rods S S S S. These supporting-rods are connected to the reciprocating chests (J and O, and serve to support the chests and to allow them to vibrate horizontally as well as reciprocate when actuated by the reciprocating rods R R R R. The reciprocating rods R and R are made to fit and move at their free ends on eccentrics E and E, which eccentrics are permanently attached to the shaft F, with which they move in its revolution. The reciprocating rods R and R are respectively rigidly attached to the reciprocating chests C and O and operate to give the same movement to the chests which they have themselves.

The eccentrics E E are situated 011 the shaft F, so that the respective crown of each eccentric will be directly opposite to each other. These eccentrics may be made in one motion is transmitted to the machine.

piece, as seen in Fig. 3, or may be made -sep-; arately and secured to the shaft in the same relative position, as seen at Fig. 2. When the shaft revolves, the eccentrics E andE will act on the chests O and O in opposite directions to each other, and thus counteract alljarring and shaking of the framework, of the machine, which would otherwise be very great when the machine runs at a very high rate of speed. Thus the eccentric E throws the chest 0 outward at the same time that the eccentric E throws the chest 0 outward, and the eccentric E throws the chest 0 inward at the same time that the eccentric E" throws the chest 0' inward, and the jarring which is produced by the movement of the chest 0 is counteracted by the movement of the chest 0 in an opposite direction. There are two sets of these eccentrics, one set .situated near one end of the shaft F and the other set situated near the other end, each set arranged to move in unison with each other.

These sets are designated as V and V. This is done to give strength and durability to the machine.

The shaft F is journaled to the frame-work,

and is provided with a pulley P, by which It is also provided with a loosepulley P to carry the belt in the usual manner when the machine is not in motion. f w 4 V The reciprocating rods R and R are respectively attached to the chest-s O and C in a permanent manner, so that when the rods reciprocate in their movement on the eccentrics the chests will likewise partake of the same reciprocating movement, which is very desirable in treating sealed cans of milk or other articles which it is desirable to submit to a short and rapid movement. These chests are each provided wit-h a lid L and L, which are held firmly against the body of the chest by a wedge \V and V, which pass through ordinary clevises D and D, attached to the sides of the chests. Thus when the chests are each filled with sealed cans of milk or other substance which the operator desires to submit to a rapid and short reciprocating movement, the lid is put on and the wedges V and l driven through the clevicesD and D, respectively, and bind the lids close to the body of the chests and hold fast whatever is desirous of being subjected to the movement of the chests, whether it be in bulk or confined in cans. IVhen the chests are filled and closed and the shaft F set in rapid motion, the eccentric E will throw the chest 0 out at the same time the eccentric E will throw the chest 0' out and draw them in at the same time and transmit to the chests O and O the exact opposite movements to each other, so that the resisting force of one will counteract the resisting force of the other and there will be little or no lateral strain on the journals of the shaft F, and consequently no jarring transmitted to the frame-work of the machine, which dispenses with all jarring of the building and injurious effects of the same, as well as preserves the frame-work of the machine intact.

I am aware that machines have heretofore been constructed for various'purposes wherein there were chests or crates adapted to hold cans of milk or other articles, and which were actuated back and forth in a rapid manner in order to agitate the contents of the cans, and that some of these machines were provided with a shaft having eccentrics on the same and provided with rods connecting the chests or crates with said eccentrics, whereby the rapid back-and-forth movement was transmitted to the said crates or chests holding the cans. These all had the crates or chests arranged on one side of the actuatingshaft and so constructed that they were all moved in the same direction at the same time, which constructions allsubjected theactuating-shaft to great lateral strain and transmitted all the jarring caused by the rapid movementof the chests or crates to the frame-work and building in which the machine was situated. By reason of this great lateral strain on the shaft and the jarring and jerking movement being transmitted to the frame-workand the building the machine is difficult to anchor, and both the machine and building soon become worthless or greatly damaged if the machine is run atsufiiciently high rate of speed to do satisfactory work. If, on the other hand, these machines are run at such a low rate of speed as to insure the life of the machine they will not perform the work required.

To liquidize milk in cans it requires both rapid and short vibrating movements of the cans containing the milk, which no machine heretofore made can have without rapid destruction of the machine and injury to the building. I do not lay claim, therefore, to a machine which actuates the chests all in the same direction at the same time, as they will not attain the same objects secured by my invention. I overcome all of these objectionable features in other machines by arranging two crates or pairs of crates of about the same resistance, one on each side of the shaft, and adapt them to be actuated in opposite directions at exactly the same period of ti me, so that the resistance of the one chestwill counteract the resistance of the other, and thus avoid all strain on the shaft and all jerking and jarring of the frame-work and building, and at the same time I am enabled to communicate the rapid vibratory movement to each chest so essential to liquidizing milk in cans.

Now what I claim, and for which I ask Letters Patent to be granted to me, is-

A machine for liquidizing canned milk, consisting of a frame, two chests adapted to hold a quantity of canned milk in cans suspended in said frame, a rock-shaft journaled in said frame and provided with rocking devices arranged to move opposite to 'each other at the same time, and connecting-rods separately connecting said two chests with said rocking devices on the rock-shaft, all operating to rapidly move said chests and their contents back and forth in opposite directions at the same time, for the purposes set forth.

GEORGE ROTH.
